  • Sym-1 plus EPROM

  • One of the popular chip formats in the 70's and 80's were the ubiquitous EPROMs (Electrically Programmable Read Only Memories). They had very good memory density at the time and were accessible technology for hackers and OEMs alike. They had the advantage...
  • Eureka!

  • After I convinced myself that the emulator was probably OK, I turned back to the ROM.  But after I found yet another ROM image online, and it turned out to be identical to the other three, I have to rule out bad ROM as well. Just as well as I was...
  • ESPduino or Neopixels memory leak?

  • So after several days trying diffrenet approaches for communication beetween server and ESP8266 we finally got the last bit working on the project (have some back logging to do here at hackaday.io), MQTT over a ESP8266 to a Teensy 3.1. The resulting...
  • On I/O

  • The biggest challenge right now is I/O into the system. I'd eventually like to support KeyboardLCDSerial / UART for attaching modems and other such thingsCompact flash driveA Counter/Timer Circuit (CTC) Last night, I realised I could use a handful of...
  • Backplane

  • I decided that interface between ZIF-socket and host machine will be implemented with help of this antique ISA backplane manufactured in 1984 (I bought it for about $20 last month):I cut out it a little to remove part with pull-up resistors, because...
  • Voices of the past, speak up!

  • Introduction Talker/80 offers: DECtalk-Based Text-to-Speech (TTS) Synthesis: the Epson S1V30120 TTS chip on the utilized mikroBUS "TextToSpeech Click!" daughterboard from MikroElektronika implements DECtalk v5 - a natural sounding speech synthesizer...
  • OPS ENUMERATED - Draft

  • This represents a complete OPCODE list with 14 Constants (int values) available and 10 Labels (byte values) available for creating subroutines. Constants were favored over Labels, but this is up for evaluation. NOP and HCF were both added to the official...
  • Control Board FPGA Pinout

  • I might be missing a few connections yet which I'll correct as I come across them, but here is the pinout of the XC3S250E FPGA on the control board.  Note that the SRAM and the Flash share an interface bus.  Also note that the JTAG interface...
